LIFTING APPARATUS,

Specification of Letters Patent. Patented S t. -28 1909,

Application filed May 18, 1908, Serial N0. 483,469- Renewed March 2, 1909. Serial Nd. 4,80,972.

To all whom it may concern:

Be it known that I, T .HOMAS MARSHALL SMITH, a citizen of the United States, residing at Baltimm-e, Maryland, have invented certain new and useful Improvements in Lifting Apparatus, of which the follt-nving is a specification.

My invention herein described is designed to lift, support and move invalids, with safety, convenience and without. discpmtort or alarm.

I have fu lly described herein the general structure and the details, as well as the uses and adaptations, and in the claims specified what I regard as of my own invention.

The structure is illustrated in the accompanying drawings, in which,:

Figure 1 is a central vertical sectional view of the invention with parts in elevation. Fig. l is a View of a detail. Fig. 2 is a plan view of the turn table or support for the frame or beam which supports the invalid. Fig. 3 is a detail view of a supporting leg for the apparatus. Fig. 4 is a plan view of the apparatus with parts in section and parts omitted. F ig. 5 is a view similar to Fig. l a quarter turn therefrom. Fig. 6 is a detail view of the stationary base with which my apparatus may be used. Fig. 7 is a plan view of one section of the support or hanger for the frame or beam from which the invalid is supported. Fig. 8 is a side view of the member shown in'Fig. 7. Fig. 9 is a. side view of the turn table member adapted to be supported in a pair of members such as shown in Fi 7. Fi 10 is a' plan View of the parts shown in Fig. 9. Fig. 11 is an end view of the parts shown in Fig. 10. Figs. 12, 13 and 14 are detail views relating to the block for supporting the cross arms. Figs. 15 and 16 are detail views of the swivel support or head to which the cross arm is fixed. Fig. 17 is a perspective View of :the apparatus with .one of several forms of direct supports for the patient. Fig. 18 is another view of the apparatus. Fig. 19 is a detail view of the locking means. Figs. 20, 21,22 and 23 and 26 are views of details. Fig. 24 is a top plan view showing the relations of the wheels and axle and the pivoted legs, and Fig. 25 shows a side elevation .of the same with the base and operating lever. Figs. 24 and 25 show another form oftruck.

In the drawings, A represents the base of the apparatus. It is of substantial size and weight, contains the lifting mechanism proper, and holds also the plunger rod which forms the upper part of the standard which.

carries the anm that. directly supports the weight of the patient.

Emitting for the present further reference to the baseand power Iproducing means therein, I point out that the plunger B rises from the base and carries an arm 'C. The plunger is preferably the piston of a hydra-ul=ic lifter; is round and moves vertically or turns in the .base. The arm (1 is of T iron held with its central Web in vertical plane, in a bracket b ted t the plunger or standard. In further bracing against the strains, sometimes heavy, 1 tie i t-he free end of the arm to the top of the standard .by rod 2.

Upon this arm is carried the support for the pa ient, n such manne as o provide for the freest movements, rotary .on the arm carriage and longitudinal of the carriage .on the arna. The first movement is the elevation of the plunger carrying the patient and the .direct supports for the patient connected with the arm.

The carriage 3 is suspended upon a pair of wheels which run on the horizontal flange of the ,arm. To this carriage is connected the part which controls :the patient, holds him from tipping in any direction and yet permits free movement both rotary and longitudinal. This part unay be varied inform, but is maintained under all circumstances in substantially the same horizontal plane. A very simple and effective form is shown in the drawings. A steel beam D of T form is pivotally connected at its center with the underside of the carriage. The carriage is snugly held .on the arm by anti-friction rollers 55, so that it may move freely but cannot tip and the beam D is swiveled on the carriage underneath by a fifth wheel construction which permitsthe turning of 'theabeam, to any extent in a horizontal plane,

tientsor different conditions of the same patient. Sometimes the patient needs the support of a bed, such as an ordinary stretcher Fig. 1-8, with rigid side bars.

Sometimes he requires a series of straps Fig.

17 and sometimes may be better held in a sitting position by a simple broadband.

'But the same security is afforded by the E, adjustable on the beam D. These bars are of steel of the form of T iron and are in length substantiallyequal to the width of the bed frame or direct. patient support. They are pivoted to blocks 8, which slide on the horizontal flanges of'the beam D and are provided with set screws 9 by which the cross bars may be fixed on the beam at desired points. The central cross bar E is connected to the main beam D between the depending arms 10 of the turn table or fifth wheel. When a bed form of direct support is used the chains one for each end of each cross arm are connected thereto by snap hooks Fig. 17. This, as is well known, may be made separate so as to be put under the patient lying on an ordinary bed, and when the connections are made the lifting power is applied and the patient lifted and supported on the movable bed. If the apparatus be at the head'of the ordinary bed the patient may be swung into various positions, as for example, in front of a window. It will be observed that the whole weight is borne upon the beam which is held firmly .on the fifth wheel or turntable and therepressure, while his hands are free to handle the patient. The arms 10 of the fifth wheel or turn table afiord bearings or connections between the turntable and the horizontal beam at separated points diametrically opposite each other in respect to the turn table, distributing the strain and rendering the construction capable of resisting any twisting .strain in any direction to which the parts may be subjected by the preponderance of weight being first at one point under the beam and then at another.

The support 3 is composed of the upper part supported on the arm C and which is preferably, though not necessarily, arranged to travel thereon, and the lower turning part.

The upper part is composed of two sections 11 and 12 divided from each other vertically and located upon opposite sides of the arm C. Each of these sections has a post 13 for one fits snugly beneath the lower face of the beam D.

of the track wheels 14 and each has a semicircular socket 15 which, whenthe two sections are brought together provides a complete socket for receiving the head or swivel 16 of the lower section of the support, this 0 lower section constituting the turn table, it having an elongated plate 17 to bear on the underside of the support 3. The sections 11 and 12 of this support 3 are heldtogether by bolts 18 and the base part 19 of thissupport furnishes the member or plate circular in form against which the turn table works. The head of this turn table lies closely beneath the bottom surface of the beam C. The carrier or support 3 is further provided 0 with rollers 5 bearing on the underside of the arm C, thus maintaining the support against tipping or displacement, while at the same time permitting it freedom of movement. The rollers 5, 5 prevent lateral s5 displacement by bearing against the side edges of the beam. The arms 10 which reach down from diametrically opposite points from the turn table are provided with alined openings of substantially the same shape as the cross sectional shape of the beam D and this beam is fixed rigidly in these arms by employing a filling of Babbitt metal between the angle iron beam and the wall of the opening in thehanger or arm 10. By use of these arms or of the turn table having connection with the beam D at diametrically opposite points or along its diameter and by the use of the turn table which gives a broad swivel bearing, I am enabled to place the Weight at any point along the beam, the patient, sitting, lying flat or being in a recumbentposition, without strain upon the support connected with the arm C;

The blocks 8, which hold the cross arms E, are provided with fingers 20, grasping the flanges of'the beam D. These blocks have each a socket 21, which receives the head 22, of a hanger 23, which is provided with an opening 24 angular in cross section to correspond with the cross sectional shape of the cross arm, which arm is fixed therein by babbitting. The head 22 is not of complete circular form, having opposite edges straight and parallel, to fit between the pairs of fingers 20, after which, by turning the hanger 23, the head 22 will take under the fingers 20, and lie in the socket in the block 3, so as to turn therein to adjust the cross arm' to any desired angle in relation to the supporting. 12o beam D, it being understood, however, that the cross arm can be adjusted only in a hori, zontal plane. The head 22of the hanger 23 The support, or carriage 3 may be set in any desired position by the hand screw 9, and the cross arms may be set in any desired position along the beam D and at any desired horizontal angle thereto by a hand be held from turning in the block 8 and the.

block 8 will be held against movement along the beam D. v

Reverting to the standard or plunger B, this moves vertically in a cylinder F screwthreaded at its lower end into a block :orsu-pport 26 which is bolted at 27 to the base A. Within the cylindermoves the piston 28, which is swiveled at 29 to the lower end of the plunger so that said piston W111 accommodate itself to any irregularities in the bore of the cylinder. The cylinder is braced above its point of connection with the base by means of a shell or casing 30, held bythe bolts 27 to the base, the block or support 26 being bolted between this shell and the base.

The base A has bolted thereto a casting 28, the a-rnrof which is slotted at 29 to receive the upright flange 30 of an angle iron leg which carries a caster wheel The base has pivoted thereto at diametrically opposite points to swing in a horizontal plane a pair of legs 32, these being located about 90 distant from the fixed leg. Theseswinging legs are composed of castings or brackets adapted to receive the angle iron member of the leg like the fixed leg above described, and in addition they have each an extension 33, to which a link 34 is pivoted, connecting the swinging leg di-.

rectly to the arms of a fork 35 of a handle or lever 36, the said fork being pivoted at 3-7 to the base. The lever 36 when in the upright position of Fig. 1 holds the legs in extended position, as shown 1n Fig. 4. In this position the lever will be retained by a catch 87 thereon, which is provided with an inclined end 38 adapted to fit an opening in a bolt 39 which slides in a casing composed of two sections 40 and 41, the said bolt being pressed. upwardly by a spring 42. \Vhen the legs are in extended position, they afford.

, trols the lock of the hand lever and consequently of the movable legs, .and for this purpose I provide a collar or head 43 at the top of the cylinder F, said head being splined to the standard or plunger B to rotate therewith, the spline key being indicated at 44. This collar does not rise or fall with the plunger, but merely turns on the cylinder head 43* fixed at 43" to the cylinder. It is provided with an opening at 45 adapted to cooperate with the upper end of the rod 46, guided in the cylinder head which rod connects with the bolt 39 above described for controlling the locking or unlocking of the hand lever, and this head or collar also controls the locking or unlocking of the rotary standard B to prevent or allow the movement of the arm 0 in a horizontal plane. When the arm C is moved to a position in the same vertical plane with the fixed leg, the opening inuthe collar is presented to the locking rod and said rod will move upwardly to engage the said opening and thus lock the arm C in this position, so that the center of gravity is at some point in the same vertical plane in which the fixed leg extends. The locking of this arm Gin this position results at the same time with the unlocking of the hand lever so that this may now be swung downwardly to fold the movable legs from their extended position to the position indicated in dotted lines in the plan View of the drawings, and when in this position the apparatus may be moved about in the ward or from room to room through a comparatively narrow door way, and al-v the arm C. in a horizontal plane it will be necessary first to lift the lever 36 to its upright position in order that its inclined catch will act against the sliding bolt and draw the same downwardly, together with the locking rod so as to release the said rod from the rotatablehead 43, and this upward movcment of the hand lever will immediately ex tend the folding legs to their widely separated positions. Now, as soon as the arm C has been adjusted however small a distance to either side of the vertical plaiie of the rigid leg, the solid portion of the head or plate 43 will bear upon the upper end of the locking rod 46 and keep the same pressed downwardly to maintain the locking bolt in proper position to retain the operating lever in its uppermost position and consequently with the folding legs extended. The hand lever is connected by the links 45" t6 with the base, the said links being, pivotally connected together and pivoted to the lever and to the-base.

At the point where the rod 2 passes I through the upper end of the plunger or standard 13, I place a reinforcing head or block 47.

I may employ any suitable form of hydraulic lifting apparatus arranged in the base, my present invention not bein limited in this respect and this hydraulioli t may be operated through a lever 48.

It will be observed that the cylinder extends a considerable distance above the upper end of the hand lever to furnish an elevatcd support for the standard, and this is rendered possible while at the-same time the lock for the lever is provided, by means of the elongated rod '46extending from the locking bolt to the head or collar of the cylinder. The lever when turned downwardly may be used for pulling or pushing the apparatus from place to place, and this is rendered stable and the power supplied is distributed by means of the jointed link The apparatus may be set up on the floor and fixed in relation to the couch or bed, for which pur ose it may have a stationary base instead 0 a rolling base as illustrated.

The block 26 is intended for use with any form of base either fixed or movable, and for this reason the block is removably connected with the base and it carries the cylinder of the elevating mechanism. The n per casing may also be used with any su1table form or base. I show in Fig. 6 a stationary form of base A which may be used.

interchangeably with the movable form of base shown in the other figures.

The beam D may be held rigidly to the arm C if it is desired for any purpose to prevent the beam from swinging in a horizontal plane, and for this purpose I provide a snap hook 50 on the end of the beam D adapted to engage a ring 51 secured to the arm C or its bracket as indicated in Fig. 17. By adjusting the block or carriage support 3 along the arm 0, the snap hook 50 can be engaged with the ring and the beam D with its supporting means held rigidly in relation to the arm It will be understood that any form of extensible or folding supports or legs may be used and I do not limit myself to the pivoted form of these extensible or collapsible sup porting means.

The structure which I have called a turn table is not in the ordinary form of a turn table, and by this term I mean a structure accomplishing the functions of the. device which I have described. I In order to aid in centering the arm 0 in respect to the fixed leg and to quickly bring these parts in such relation that the opening at 45 will aline with the locking bolt 46, I provide registering marks or pins at 43" on the collar 43 and cylinder head 43", so that the attendant by simply bringing these zontal movement of the arm C so that itwill not swing past the vertical planes in which the folding legs lie when in extended position, I provide a stop pin 52 on the collar 43 which extends down into a groove 1;: the head .43 which is secured to the cylinder and in this groove I place two stop pins 53 which limit the rotary movement of the splined collar 43, and consequently of the horizontal arm 0.

I show at 54, Fig. 21, an opening in the cylinder head through which access may be had to the interior thereof for fastening a collar 55 on to the depending central portion of the collar 43 as shown in Fig. 23, screws being used to fasten this collar 55 in place which screws are threaded into openings in the collar 43 at 56 Fig. 20. I indicate this screw in dotted lines Fig. 23 though slightly displaced for convenience of illustration. The hole 54 may be plugged up after the arts are secured together. I also show a ushing at 57Fig. 3 which may be held in place within the collar 43 by pins inserted throu h the holes 58,Fig. 20.

The trea e 48 is pointed at 48 whereby it may be swung up out of the way.

In the form of truck on which the apparatus is supported and moved, I provide a pair of wheels 60, mounted on an axle 61 and arranged outside of the base so that wheels larger andmore easily moving than the ordinary caster wheels may be used. The

' axle forms a fixed support on one side and a to be moved or outward to,enlarge the base when the lifting mechanism is used The wheels 63 are swiveled as casters. The pivoted ends of the legs 63 are provided with the extensions 33 connected to the handle in the same manner and with the same effect as in the form heretofore described.

A brake shaft 65 is mounted in the base and at its ends has fixed thereon arms 66, carrying brake shoes 67 This shaft has an intermediate fixed arm 68 connected to a bell crank lever 69 on a fixed pivot, one arm of the lever being arranged to be operated by the foot of the attendant in applying the brake and with the legs thus pivoted they may be spread to pass under the cot without interfering with the ventilator or the fixture under the bed, and at the same time by motion of the foot the apparatus may be arrested and held in place. This brake may be also operated automatically as illustrated in Fig. 26 in which the arm 68 is connected with an extension 70 of the handle 36 through a spring 71. With this arrangement the lifting of the handles to spread the legs at the same time and movement puts on. the brakes and as the handles are locked in place the brake is locked by the same mechanism.
